Trust Assessment
finance-skill received a trust score of 65/100, placing it in the Caution category. This skill has some security considerations that users should review before deployment.
SkillShield's automated analysis identified 4 findings: 0 critical, 1 high, 3 medium, and 0 low severity. Key findings include Missing required field: name, Sensitive environment variable access: $HOME, Unquoted variable in echo statement leading to command injection.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 13, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings4
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Unquoted variable in echo statement leading to command injection The `SOURCE` variable, which is derived from the first command-line argument (`$1`), is used unquoted within an `echo` statement. If an attacker can control the value of `$1` (e.g., by providing a malicious string like `'; rm -rf / #'` as the source name), they could inject and execute arbitrary shell commands. Always quote variables when expanding them in shell commands, especially in `echo` or `printf`. Replace the vulnerable line with `printf "Added %s transactions from %s\n" "$(echo "$NEW_TXS" | jq length)" "$SOURCE"` to prevent command injection. | LLM | scripts/add-transactions.sh:25 | |
| MEDIUM | Missing required field: name The 'name' field is required for claude_code skills but is missing from frontmatter. Add a 'name' field to the SKILL.md frontmatter. | Static | skills/safaiyeh/finance-skill/SKILL.md:1 | |
| MEDIUM | Sensitive environment variable access: $HOME Access to sensitive environment variable '$HOME' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated. | Static | skills/safaiyeh/finance-skill/scripts/add-transactions.sh:5 | |
| MEDIUM | Sensitive environment variable access: $HOME Access to sensitive environment variable '$HOME' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated. | Static | skills/safaiyeh/finance-skill/scripts/query.sh:6 |
